The Nirvana frontman, who was found dead at his home with a shotgun wound in his head in 1994, is thought to have written the unruly note accusing "b**** with zits" Courtney of "siphoning" all his money.

It reads: "Do you Kurt Cobain take Courtney Michelle Love to be your lawfully shredded wife.

"Even when she's a b**** with zits and siphoning all yr[sic] money for doping and whoring."

The note was scrawled on paper from the Phoenix Hotel in San Francisco but is undated and the context of the note may never be understood.

It was released by Seattle police last month along with a number of items from the scene of his death after a public request was approved.

Cobain was found dead at his home Lake Washington Boulevard on 8 April 1994, aged 27.
